HO12 | Timber Construction Details | Update Information


Version 02/17


Correction

Error division by zero with full-thread screws fixed.
Adjustment of the material settings in the user interface.


Version 01/17


Eurocodes

New Timber due to EN 338:2016 implemented.


Version 02/16


Eurocodes

Glulam according to EN 14080:2013 implemented for Germany and Italy.
The "old" Glulam timbers are marked with * (for example GL24c*).


Version 01/16


Eurocodes

BS EN 1995:2012 and ÖNORM EN 1995:2015 implemented.

Correction

Constructive restricting recess height to beam height according to DIN can be deactivated.
Haunch with upper corner cut is possible now.


Version 02/15


Addtion

Implementation of DIN EN 1995:2013 in combination with EN 1995:2014.
Preset design standard can be defined in the project properties.


Version 01/15


Correction

Optimized start behaviour with Eurocode.


Version 02/14B


Correction

Input of FtRk of full threaded screws: will be taken correctly.
Correction in output of full threaded screws: Ftensk is [N] instead of [N/mm²].
output of full threaded screws in NA-D was sometimes not shown. This is corrected.


Version 02/14A


Correction

Programm could be terminated on right click in graphics.


Version 02/14


Improvement

The proof of shear-stress with reduced cross-section at support will be done in case of reinforced cross section.

New Feature

For combinations with wind in german NA, you can optionally activate the use of kmod as the average of short and instantaneous.

New Code

DIN EN 1995-1-1/NA:2013-08


Version 01/14


Translations have been improved.


Version 01/13B


Corrections in output

The output has been improved for fasteners, that are invalid due to given conditions.


Version 01/13A


SPAX Z-9.1-519:2012-01 implemented.


Version 01/13


internal modification


Version 02/12C


DIN EN 1995

The permissible shear stress can be increased due to NCI for 6.5.2, equation (NA.60).


Version 02/12B


Correction

The material selection box has been corrected.


Version 02/12A


Licence checking for EN 1995-1-1 has been corrected


Version 02/12


Proof of Shearing of reduced cross section

The Proof of Shearing of reduced cross section has been added.


Version 01/12


Notchings with Haunts

For notchings with haunts now the combined stress proof of side-grated edges is considered, too.
The proof is added for DIN 1052:2004, 2008 and EN 1995-1-1 with all National Annexes.


Version 02/11


EN 1995

Depending on the licence nochtings and holes can be proofed acc ÖNorm B 1995-1-1 and acc DIN EN 1995-1-1/NA:2010-12.
Unfortunately in some codes are missing some rules in details. In those cases the missing rules are adapted by the rules acc DIN 1052:2008. Please refer to the documentation of the program!

Counter-sunk screws/threaded bolts

For screws it is possible to consider that screws are - e.g. due to fire protection - counter-sunk for the length cf.
It can be considered for reinforcement of nochtings as well as for holes.
Even glued threaded bolts and SPAX-screws can be counter-sunk.
Counter-sunk fasteners can be considered acc DIN 1052:2004, 2008 and EN 1995.

Correction

The conclusion by analogy for the edge distance to the edge of the hole (a3,x=2,5*d) s only valid for predrilled screws.
For not predrilled screws the common distances of axial stressed scews are valid!


Version 01/11A


SPAX-screws

The new version of the Technical Approval for SPAX Z-9.1-519:2011-03 is now implemented.

Furthermore the minimum edge distance to the edge of the hole has been changed in Picture 40 of DIN 1052:2008 against DIN 1052:2004. The values have been adapted acc DIN 1052:2008.

Correction

The minimum screw-in length at reinforcing of holes has been calculated too large.
As a result of this sometimes the minimum srewn-in lenght was greater than the height of the beam.
The calculation of the minimum screw-in length has been corrected; due to this now it is again possible to proof short(er) screws.
For screws that have been great enough for the too-large-calculated screw-in length the results are the same-
but for shorter screws the bearable capacity force of the screw is getting less than in the old version! But nevertheless in this cases the minimum screw length has been broken!


Version 01/11


The service function for the distance e in DIN 1052/A1:1996 has been corrected for beams with notching on the top side.


Version 02/10


Design situations

For DIN 1052:2004, 2008 and EN 1995 with the available National Annexes it is optionally possible to consider the persistent/transient design situation or the accidental design situation.

ÖNorm B 1995-1-1:2010

Depending on the licence the proof acc ÖNorm B 1995-1-1:2010 is available.
Attention! Please refer to the documentation of the program due to adaptions of missing parts of the euro code.


Version 01/10


internal modification


Version 03/09C


correction of effective length of Spax-screws


Version 03/09B


remarks added in output.


Version 03/09A


correction for notching with haunch

Beams with notching on the bottom side and a haunch have been calculated with the wrong reciprocal value of Epsilon.
For s bigger than a the error was uncritical, but for s smaller than a too big admissible shear strength have been considered.


Version 03/09


Internal adaption.


Version 02/09A


Input

Now you can change the code while output is active.

DIN 1052:2008

DIN 1052:2008 is available, if licensed.


Version 02/09


Input

Instead of the effective bearing length the program requests for the length of the bearing plate and the effective value is calculated by the program.


Version 01/09A


Output

Invalid conditions for proof of notching is noticed in the output.


Version 01/09


Correction

If a screw is longer than the beams height, the program calculated with a too large effective length. Now the length of screws is checked and maybe reduced to beam height.

ASCII-Interface

A new ASCII-Interface is available now.
